Specification of Letters Patent.

Patented July 12, 1919.

Application filed May 14, 1909. Serial No. 495,880.

To all whom it may concern:

Be it known that I, SAMUEL BEY, a citizen of the United States, residingat Bennington, in the county of lVyoming, State of New York, haveinvented certain new and useful Improvements in Windmills; and I dohereby declare the following to be a full, clear, and exact descriptionof the invention, such as will enable others skilled in the art to whichit appertains to make and use the same.

This invention relates to Wind mills and has a special reference to awind mill of the horizontally revoluble type.

One object of the invention is to improve the general construction ofwind mills of this character.

Another object of the invention is to provide an improved means forregulating the vane openings of mills of this character.

A third object of the invention is to provide an improved form ofmanually controlled governor mechanism for mills of this character sothat the speed may be varied at will and yet kept constant withoutreference to the force of the wind.

WVith the above and other objects in view as will hereinafter beapparent the invention consists in general of an outer casing providedwith wind gathering vanes, a wind wheel revolving within the outercasing, and certain improved vane regulating mechanism.

The invention further consists in certain novel details of constructionand combina tions of parts hereinafter fully described, illustrated inthe accompanying drawings, and specifically set forth in the claims.

In the accompanying drawings, like characters of reference indicate likeparts in the several views, and Figure l is a side elevation of the headof a wind mill tower equipped with a mill constructed in accordance withthis invention. Fig. 2 is a vertical'median section on the line 22 ofFig. 1. Fig. 3 is a bottom plan View of the outer casing and vaneactuating mechanism. Fig. 4 is a detail view of the governing mechanismshowing the position assumed by the governor when the outer casing isentirely closed.

The numeral 10 indicates the legs of a wind mill tower and upon theselegs is supported a top platform 11. Secured in spaced relation to thetop platform 11 by means of suitable bolts 12 and sleeves 13 is an outercasing bottom plate 14. An outer casing top plate 15 is held in spacedrelation to the bottom plate 14 by means of suitable bolts 16 providedwith spacing sleeves 17.

Between the plates 14 and 15 and rotatably mounted therein are a seriesof shafts 18 to each of which is fixed a wind gathering vane 19 soarranged that the successive vanes overlap each other to make asubstantially cylindrical casing when said vanes are closed. Each of theshafts 18 is provided on the end beneath the plate 14 with an arm 19which is fixedly mounted on the shaft.

Extending through the lower plate 14 of the casing and held in asuitable bearing 20 located thereabove and in a suitable bearing 21located beneath the plate 15 is a wind wheel shaft 22 whereon are fixedspaced end plates 23 between which are rigidly mounted a series of windvanes 24. At 25 is a lower platform and on this platform is mounted aguide bearing 26 through which extends the shaft 22. The shaft 22 isfree to revolve in these bearings and as the wind enters the outercasing, being directed therein by the guide vanes 19, the air strikesthe windwheel vanes 24 and rotates the shaft 22.

Rotatably mounted upon the shaft 22 and immediately beneath the bearing20 is a block 27 which supports a circular plate 28 having a series oflinks 29 connected thereto at one end while the other ends are connectedrespectively to the various arms 19. It will be observed that thelengths of the arms 19 and links 29 are so regulated that at all timesthe links and arms occupy an angular relation which is substantially aright angle to each other. Bars 30 are spaced on opposite sides of theshaft 22 and are firmly attached to the bottom plate 14. These barsextend below the plate 28 and for the purpose of permitting them to passthrough the plate as well as for the purpose of limiting the movementthereof this plate 28 is provided with a pair of oppositely disposedconcentrically arranged arcuate slots 81 through which the said barspass. It will now be plain that, as the bottom casing plate 14 isrigidly attached to the platform 11 and cannot therefore be rotated, therotation of the plate 28 will move the arms 19 and cause the vanes 19 toopen or close according as the arms are moved outward or inward. Inorder that this may be accomplished by governor actuated mechanism theblock 27 has projecting downward therefrom a pair of opposed spiriformmembers 32. Upon the shaft 22 is mounted a bearing 33 provided with aplate 34 fixed thereto and rising from this plate 34 are a pair ofrectangular U-shaped members 35 which closely embrace the bars 30 andspiriform members 32. These spiriform members 32 are further arranged sothat they do not touch the shaft 22 but form a species of double wormtherearound. By reason of this construction if the bearing 33 be moveddownward from the position indicated in Fig. 2 it will assume theposition shown in Fig. 4 and since the members 35 are held from rotationby the downwardly projecting bars 30 the spiriform members 32 will becaused to rotate and carry with them the plate 28 with the consequencethat the guide vanes 19 will be open or closed according to thedirection of movement of the bearing 33 and the amountthereof.

At 36 is a sleeve which surrounds the shaft 22, said shaft being freelyrotatable therein and this sleeve is preferably provided with a ballcone 37. A cup 38 is screwed into a cylindrical recess made in thebottom of the member 33 and serves to hold the wall 39 securely againstthe ball cone 37.

At 40 is a sleeve provided with a shipper fork groove 41 extendingtherearound and this sleeve 40 is held on the shaft 22 to be freelyrotatable therewith. Secured at their upper ends to the lower end of thesleeve 36 and at their lower ends to the sleeve 40 are a plurality ofspring members 42 each of which has attached intermediate its ends agovernor ball 43. While the sleeve 40 rotates with the shaft 22 it issplined on that shaft in such manner that it may slide longitudinallythereof. In order to provide for the proper positioning of the sleeve 40along the shaft 22 there is mounted on the platform 25 a standard 44having a forked upper end and supporting a shipper lever 45 which hasits end engaged with the groove 41 of the member 40. The other end ofthis lever 45 has connected thereto a reach rod 46 which is provided atthe foot of the tower with any suitable mechanism for moving the lever45 and looking it in the adjusted position. This mechanism is not deemednecessary here to be shown as the same forms no part of my invention andany of the ordinary devices commonly used for such pur poses may beutilized in this case. In any event when the position of the sleeve hasbeen manually adjusted it is intended that there shall be some form oflocking mechanism to retain it in such adjustment until such a time asit is desired to manually readjust the same.

In order to understand the entire operation of the device let it besupposed that the sleeve has been manually adjusted to the positionshown in Fig. 2. In Fig. 2 the vanes 19 are indicated as wide open. Nowso long as the wind remains moderate the balls 43 will lie close to theshaft 22. If, however, the wind increases the wind vanes 24 will rotatethe moving wheel more rapidly and cause the balls 43 to move outward bycentrifugal action from the shaft 22. This will cause the members 35 tomove downward since the member 40 cannot move upward by reason of thepull rod 46 being fixed at its lower end. ward they rotate the members32 as previously described and this causes the plate 28 to rotate andpartially closes the guide vanes 19. It will be noted that the amount ofclosure of these guide vanes depends entirely upon the speed of rotationof the shaft 22 so long as the sleeve 40 remains fixed in any position.In this manner, therefore, the speed of rotation is regulated within thelimit of the sensitiveness of the governor.

If it be desired to increase the speed of rotation from the arrangementshown in Fig. 2, it is merely necessary to raise the sleeve 40 by meansof the pull rod 46 and lock it in its newly adjusted position. This willcause the governor ball 43 to move outward and will consequently placethe springs 42 under tension. Now as these springs have already beenplaced under tension by the upward movement of the sleeve 40 it willrequire a greater force to move them out than would be the case if theywere not under tension as indicated in Fig. 2, and consequently theguide vanes 19 would be held fully open until the speed of rotation ofthe shaft 22 had become sufficient to develop the greater centrifugalforce required to move the ball 43 farther out. As soon, however, asthis should take place the vanes 19 would be closed in the mannerpreviously described. It will thus be seen that the device is not onlycapable of being automatically controlled but may be ,manually adjustedto varying speeds while at the same time retaining the automatic controlby the governor mechanism. There has thus been provided a simple andefficient device of the kind described and for the purpose specified.

It is obvious that minor changes may be made in the form andconstruction of this invention without departing from the materialprinciples thereof. It is not therefore desired to confine the inventionto the exact form herein shown and described, but it is wished toinclude all such as properly come within the scope of the appendedclaims.
